Customizing Your Seasons

There is a single screen at which you can customize your seasons to your specific liking. To access it, simply go into the main options screen by clicking the "..." button in the bottom-right corner, either inside a save or from the main menu. From there, click the second tab from the right. (Note that if you have The Sims 3 Supernatural installed, this tab also takes you to the Lunar Cycle settings.)

Unlike in The Sims 2's version of Seasons, you cannot change the order of seasons or create multiple instances of a season for a year. However, you can outright disable any season, and you can adjust the length of each season.

If you favor a particular season, or if you're role-playing a locale, you can use these settings to adjust your experience. For example, if you're role-playing a town in Canada, you may want to extend Winter while shortening Summer. Conversely, if you're role-playing a desert town, you might want to disable all seasons except summer.

When changing the season options from the main menu, that applies to all new save files; that is, it becomes the new default. However, all save files (once saved after Seasons is installed) have their own Seasonal settings. This way, you could leave the main menu options to the developer's defaults, but then customize each neighborhood when you load it.

You can also customize whether a particular precipitation will be enabled on this screen as well. Hail, rain, snow, and fog can all independently toggled on or off.

Temperature is directly affected by which season it is, regardless of the weather you choose, and cannot be changed. If you want your neighborhood to be a little paradise, consider staying in perpetual Spring with all weather disabled. It might be a little boring like that, though!
